Hi,

Test in 2.8 and latest commit 8a98b8d0c9e99df9cf83a08cb032657531598e18 , title looks corrupt with some dummy invisible prefix string.

Test cases

$ redis-benchmark -n 10 -t GET >get
$ vim get
GET: nan^M====== GET ======
  10 requests completed in 0.00 seconds
  50 parallel clients
  3 bytes payload
  keep alive: 1

20.00% <= 1 milliseconds
100.00% <= 1 milliseconds
10000.00 requests per second

$ redis-benchmark -n 10  >all
$ vim all
PING_INLINE: 0.00^M====== PING_INLINE ======
  10 requests completed in 0.00 seconds
